Another day, another migraine

Today I woke up with a migraine. 

What a migraine is for me includes the following symptoms:
- light sensitivity
- pain behind my left eye
- pain in my jaw, mostly left side
- pain throughout my head, mostly on the left side
- the desire to insert objects into my skull in an attempt to relieve the pressure in my head
- tiredness (but this is almost a constant in my life)
- differing levels of nausea (not always, but yes for today) 

I am currently at the beginning of Day 4 of 5 of an R course. Reflecting over my life there is definitely some correlation between the two, but what evidence is there to support that this R course is the causation of this migraine?

- R is computer software, therefore I have been sitting at a desk on a computer for several days straight (Sedentary +, Posture -)
- I am not technologically inclined. Statistics and programming is a steep and stressful learning curve (Anxiety +)
- I need time in nature to replenish my energy. Doing this course means I have only had one break a day to go outside. (Anxiety +, Tiredness +)
- There was a public holiday this week, therefore my usual yoga class was canceled (Sedentary +)
- The public holiday also meant the uni was closed, but I still had to come into campus where the kitchens were locked so I could not heat up my food in the usual place,  I could not drive into campus through the usual gate. These things added time to finding a way in/out of campus and looking for a kitchen could get into (Anxiety +)
- I am in a room full of humans all day every day, regardless of what I am doing this situation drains my energy superfast, likely increased by my autism (Anxiety +, Tiredness +)
- The desk space I have here does not allow me to see the projected screen while facing my own screen face on, this leads to constantly having to correct my posture once I realise I am twisting (Posture -)

Anxiety and tiredness, a sedentary lifestyle, and bad posture are common contributing factors that can lead to migraines. 

Taking into account the usual weekly problems I face, the addition of this extra anxiety and tiredness, as well as the increased sedentary lifestyle and bad posture, it would be fair to conclude that my participation in this R course contributes a large part to the onset of my current migraine.
